Booted up MBP to this: oops!

(This is what it looked like, this is from google, tho. there was also a small square towards the bottom middle left.) 2020 Intel MBP with current Sonoma. I rebooted and it's fine. Should I do the SMC PRAM reset thingy?

MBP 2020 is Intel or M1? M1 does not have SMC or PRAM. Just turn it off.

How to reset the NVRAM, PRAM, and SMC on any Mac

If you're experiencing weird glitches with your Mac, doing a reset of your MacBook or desktop Mac could help. Here's how to reset the NVRAM, PRAM, and SMC on either an Intel or M-Series Mac.

Intel.

SMC reset won't hurt anything. But looks like a hardware issue to these eyes.

I agree. I would suspect that the graphics chip is beginning to fail.
You should run the built-in diagnostics, to see if anything is reported.

hardware failure, probably GPU or monitor cable. No resets will help

If it was a one-time occurrence, I'd just let it pass by and move on.

Do a test:
1. power down ALL THE WAY OFF
2. boot up fresh
3. does the problem recur?

REPEAT five times in succession.
What are your findings?
